Capstan equation ( belt friction equation) - calculator ...

The capstan equation or belt friction equation, also known as Eytelwein's formula, relates the hold-force to the load-force if a flexible line is wound around a cylinder (a bollard, a winch or a capstan. Because of the interaction of frictional forces and tension, the tension on a line wrapped around a capstan may be different on either side of the capstan.[...]

Mass balance - Wikipedia

The concept is the same as for a large mass balance, but it is performed in the context of a limiting system (for example, one can consider the limiting case in time or, more commonly, volume). A differential mass balance is used to generate differential equations that can provide an effective tool for modelling and understanding the target system.[...]
